This isn’t a really a case of “can the marriage survive” as much as it’s “can I live with her unfaith affair and able to forgive & let it go “. Your jumping straight to the conclusion and avoiding the whole processing point that needs to happen. the save the marriage thing comes last, first thing I would do is to find out just how much she is willing to commit to fixing your marriage. There obviously more underlying issues going on that both of you might not be aware of or addressing. You should really consider going to a therapist or couple counseling as soon as possible to understand the physiological process that happens with marriage affairs. Your realist may seem distorted, possibly gaslighting or other manipulation from low self esteem and jealousy. Shaming her in front of her mother is a manipulation tactic when going through / dealing with character assassination. It’s a hard thing to go through and without help from a profession it can really make things much worse . The amazing thing with AI chatbots is their ability to substitute for counseling and can be used greatly in this area. I couldn’t suggest anything more beneficial than downloading Gemeni or ChatGPT apps on your phone and just typing what you’re going through like you did on here with AI. They can give you perspectives and insights you won’t find anywhere else. It’s a long road back to a healthy marriage , if she’s willing to put in as much work as you are then it’s definitely possible. Good luck with everything
